Consequence

Damaged tires can fail, causing a loss of vehicle control and increasing the risk of a crash.

Remedy

Dealers will notch the existing outrigger and install an additional outrigger between the two tires to provide proper clearance, free of charge. Owner notification letters were mailed May 12, 2022. Owners may contact Keystone customer service at 1-866-425-4369. Keystone's number for this recall is 22-430.

Defect

Keystone RV Company (Keystone) is recalling certain 2017-2021 Keystone Cougar 368MBI trailers. The frame rails do not have enough cross support, which could cause them to buckle under certain side-load stress conditions.

Consequence

A buckled frame rail can increase the risk of a crash.

Remedy

Dealers will add cross braces between each spring hanger and an outrigger between the tires on the off-door side of the vehicle, free of charge. Owner notification letters were mailed July 15, 2021.

21V178000Electrical SystemMarch 16, 2021 · 31 units

Defect

The inverter may have been incorrectly wired, causing power to energize the shore power connection, when in use.

Consequence

An energized shore power connection can cause an electrical shock, increasing the risk of injury.

Remedy

The Solar Prep wiring to the 12VDC breakers located by the battery may not be connected to the protected side of the breaker.

Consequence

Since it is not connected properly to the breaker, if the Solar Prep wiring experiences an electrical short, it will increase the risk of a fire.
